Description

Technical Field

[0001] The invention relates to the technical field of chemical liquid transportation, and in particular to a heavy-duty anti-corrosion aerogel steel shell anti-corrosion thermal insulation pipe. Background Art

[0002] Traditional pipeline anti-corrosion and thermal insulation technologies, such as coating with anti-corrosion paint and wrapping with thermal insulation materials, can protect pipelines from corrosion and heat loss to a certain extent, but in long-term highly corrosive and cold environments, the effects of these traditional technologies are often unsatisfactory. In particular, problems such as the easy detachment of the anti-corrosion layer and the aging of the thermal insulation materials have seriously affected the service life and thermal insulation effect of the pipeline.

[0003] In the prior art, most of the insulated pipes are made of plastic material, because such insulated pipes are generally used in liquid transportation occasions, and liquid transportation is generally medium and long distance transportation, and pipes that are too long are not only troublesome to manufacture, but also troublesome to transport. The solution is to make multiple pipes and then splice them together. The splicing position is connected by a heat shrink sleeve. The heat shrink sleeve is a material that can shrink under high temperature conditions. When two pipes are spliced ​​together, the heat shrink sleeve is placed on the connection position, and then baked at high temperature to shrink it and stick it to the connection position so that the connection position is tightly sleeved to complete the connection of the two pipes. After the pipes are connected, sponge and other insulation materials are wrapped around the outside of the pipes for insulation. However, the existing insulated pipes are made of plastic material, which is easily corroded by liquids with corrosive effects, causing liquid leakage, and the processing temperature of heat shrinkage is high, which may cause melting or deformation of the plastic. The heat shrink sleeve may reduce the mechanical strength due to excessive processing heat. After shrinkage, the length will be shortened to a certain extent, affecting the installation. Long-term use will also cause poor adhesion, which will affect the insulation after falling off, and the corrosion resistance itself is also poor.

[0004] Therefore, how to provide a heavy-duty anti-corrosion aerogel steel shell anti-corrosion insulation pipe to solve the defects of existing insulation pipes is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] To this end, the present invention provides a heavy-duty anti-corrosion aerogel steel shell anti-corrosion insulation pipe to solve the problems in the prior art that the insulation pipe has poor corrosion resistance, the insulation material is easy to fall off, and the pipe connection material is inconvenient to use, which affects the insulation performance and service life.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0015] The protrusion is installed at the end of the pipe body, and the two ends of the protrusion are opposite to form a butt joint pipe body, and the outer side of the butt joint pipe body is covered with the insulation layer.

[0018] In a possible implementation, the fixed shell is wrapped around the outside of the two ends of the protective shell, the surface of the fixed shell is covered with anti-corrosion paint, and the fixed shell is made of galvanized steel pipe.

[0019] In a possible implementation, the fixing rope is made of a polymer material such as glass cloth.

[0020] In a possible implementation, the tube body and the limiting ring are made of steel.

[0024] The present invention can effectively solve the damage to the connecting components caused by transporting corrosive fluids through the design of the connecting components themselves with steel materials, and can effectively increase the service life of the entire insulation pipe. The insulation layer is not only attached to the pipeline, but also an additional insulation layer is added at the connection between the two connecting components to prevent heat from flowing from the connection.

DETAILED DESCRIPTION

[0035] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-Figure 7 Now, a heavy-duty anti-corrosion aerogel steel shell anti-corrosion insulation pipe disclosed in the present invention is described. The present invention consists of five parts, such as Figure 1-Figure 2 , including a fixed shell 1, a protective shell 2, a connecting component 3, an insulation layer 4 and a fixing rope 5. The outer surface of the connecting component 3 is wrapped with the insulation layer 4, the fixing rope 5 is wound around the outside of the insulation layer 4, the protective shell 2 is installed on the outside of the fixing rope 5, the fixed shell 1 is sleeved on the outside of the protective shell 2, and the fixed shell 1 is arranged on the outside of the two protective shells 2.

[0037] When the present invention is in use, a shot blasting and rust removal machine is used to remove rust from the Φ76*6 tube body 33, and then two Φ96*10 limiting rings 34 are welded to the outside of the Φ76*6 tube body 33, and the entire tube body is painted with anti-corrosion paint. After this step is completed, the insulation layer 4 is wrapped around the outside of the tube body 33, and the insulation layer 4 will be placed between the two limiting rings 34. There will be glue on the surface of one end of the insulation layer 4, and the insulation layer 4 is adhered to the outside of the tube body 33 by the glue, and then aerogel coating is applied on the surface of the insulation layer 4. After the coating is completed, a double insulation effect will be achieved. Finally, a fixing rope 5 is used to wrap around the outside of the insulation layer 4. Such a setting can effectively prevent the insulation layer 4 from falling off. After the installation of the insulation layer 4 is completed, the Φ96*3 protective shell 2 is moved along the outer surface of the limiting collar 34 so that the protective shell 2 is completely wrapped around the outside of the insulation layer 4, and then the two ends of the protective shell 2 are welded to the outer surface of the Φ96*10 limiting collar 34. At this time, use hot water or a clean soft cloth to wipe the surface of the protective shell 2, and then apply a heavy anti-corrosion topcoat on the outside of the protective shell 2 to perform anti-corrosion operations on the protective shell 2. At this time, the protective shell 2 not only prevents the corrosion of the protective shell 2, but also effectively prevents heat loss. Not only that, the insulation layer 4 can also be limited again. After that, the two ends of the pipe body 33 with the installed protective shells 2 are connected together, and then the two ends are welded together. After welding, the insulation layer 4 is wrapped around the two ends, and the fixing rope 5 is wrapped around the outside of the insulation layer 4. The fixing method of the insulation layer 4 is the same as that wrapped on the pipe body 33. The wrapping method of the insulation layer 4 is the same. The insulation layer 4 is arranged between the two limiting rings 34 of the two tube bodies 33. After the insulation layer 4 is installed, the fixed shell 1 is installed on the outside of the insulation layer 4. The center line of the fixed shell 1 is aligned with the welding points of the two ends, so that the distance between the fixed shell 1 and the two protective shells 2 is the same. In this way, when the liquid flows through the connection between the two tube bodies 33, the pressure applied to the two tube bodies 33 is the same, so that the service life of the entire insulation pipe is longer, and the situation that the insulation pipe is damaged due to high pressure at a certain place will not occur. After the fixed shell 1 is positioned, the two ends of the fixed shell 1 are welded to the outer surfaces of the two protective shells 2 to complete the connection of the two pipes. The welding adopts the electric welding process. After the welding rod and the workpiece are connected to different electrodes, the heat generated by the arc discharge melts the welding rod and the workpiece, and then cools and solidifies to form a weld.

[0038] In a specific embodiment, Figure 3The connection assembly 3 includes a protrusion 31, an anti-corrosion coating 32, a tube body 33 and a limiting collar 34. The outer surface of the tube body 33 is covered with an anti-corrosion coating 32. The limiting collars 34 are arranged in pairs and sleeved on the outer side of the tube body 33. The limiting collars 34 are arranged at both ends of the tube body 33 respectively. The insulation layer 4 is arranged between the two limiting collars 34. The inner surface of the protective shell 2 is fitted with the outer surface of the limiting collar 34. The protrusion 31 is installed at the end of the tube body 33. The two ends of the protrusions 31 are opposite to form a butt joint body, and the outer side of the butt joint body is sleeved with the insulation layer 4. The protrusion 31 is arranged to better butt the ends of the two tube bodies 33 together. The anti-corrosion coating 32 uses phenol-fluorine modified resin as a film-forming solution, and nano silicon carbide, graphite, black stone powder, heavy stone powder, yttrium oxide, etc. as fillers. The cured coating can effectively prevent electrochemical and chemical corrosion and protect the substrate for a long time in special working conditions such as acid-base with pH between 1-14, solvent gas, organic acid, organic solvent, oil and other acid-base alternating conditions. The coating has high hardness, good impact resistance, and a temperature resistance range of -45℃ to 300℃.

[0039] In a specific embodiment, the thermal insulation layer 4 is an aerogel felt. The aerogel felt is made of raw materials such as 10%-15% silica aerogel powder, 5%-8% vitrified microspheres, 7%-12% vermiculite, 13%-20% perlite, 1%-5% glass wool powder, 5%-10% polyurethane, 5%-10% potassium titanate whiskers and 50%-65% E-type glass fiber. The aerogel thermal insulation material is an aerogel felt structure formed by compounding the prepared silica aerogel powder, vitrified microspheres, vermiculite, perlite, glass wool powder, polyurethane, potassium titanate whiskers with gelling materials and other functional additives. Its thermal conductivity can be as low as 0.015~0.028w / (mk), with a low thermal conductivity and a large applicable temperature range. It has good thermal insulation performance, stable chemical properties, environmentally friendly and non-toxic, and can be recycled. The surface of aerogel felt is also coated with aerogel coating. Due to the structural characteristics of SiO2 aerogel itself, aerogel coating can effectively reduce heat transmission, improve the environment and reduce energy consumption. The nanopores and three-dimensional network structure of SiO2 aerogel destroy the heat conduction path of the matrix and have extremely low thermal conductivity. The unique nanopore structure restricts the free flow of air molecules and inhibits the convection conduction of air. At the same time, the infinite number of pore walls form the reflection and refraction surfaces of thermal radiation, which has an "infinite insulation board effect" and minimizes radiation heat conduction. In addition, SiO2 aerogel itself has good light transmittance, and can be used to prepare nano-transparent thermal insulation coatings that can be coated on glass. The coatings absorb ultraviolet light with a wavelength less than 400nm, transmit visible light with a wavelength of 400-760nm, and block near-infrared light with a wavelength of 760-2500nm.

[0040] In a specific embodiment, the outer side of the protective shell 2 is covered with a heavy anti-corrosion topcoat coating, and the protective shell 2 is fixed to the limiting collar 34 by welding, and the protective shell 2 is made of steel. The construction steps of the heavy anti-corrosion topcoat coating are to first mix the primer according to the requirements of the primer, and mix the primer and the solvent in a certain proportion to ensure the quality of the primer. Then the brushing preparation is before brushing, ensuring that the brushing tools are clean and oil-free, and preparing the brushing tools suitable for construction. After that, the primer is applied using a brush or roller. Depending on the condition of the metal surface, a single coating or multiple coatings can be selected for construction. The brushing interval and drying time are determined according to the requirements of the primer. In general, it is necessary to wait for the primer to dry before proceeding to the next process. Finally, the number of brushing times is determined according to the requirements of the primer to ensure the quality of the primer. When constructing the anti-rust primer, it is necessary to ensure that the construction environment is well ventilated. The protective shell 2 is made of steel because it has better corrosion resistance, which makes the service life of the entire insulation pipe longer and ensures that the inner insulation layer 4 is not corroded. In addition, the steel material needs to be connected by welding, and the welding method makes the pressure-bearing capacity of the connection better, effectively preventing the leakage of corrosive liquids.

[0041] In a specific embodiment, the fixed shell 1 is wrapped around the outside of the ends of the two protective shells 2, and the surface of the fixed shell 1 is covered with an anti-corrosion coating, and the fixed shell 1 adopts a galvanized steel pipe. The characteristics of the anti-corrosion coating are the same as those of the anti-corrosion coating 32. The galvanized layer of the galvanized steel pipe can effectively isolate the steel pipe from direct contact with corrosive media such as oxygen and water, significantly improving the corrosion resistance of the steel pipe. In harsh environments, such as humid, saline-alkali land or places with more corrosive gases, the galvanized steel pipe can maintain a longer service life. The galvanized steel pipe shows good toughness and ductility during the processing process, making the steel pipe easy to cut, bend and weld. In some specific occasions, such as pipeline systems for transporting flammable and explosive media, the galvanized steel pipe can provide better fire and explosion resistance. This is because the galvanized layer can isolate the shock waves generated by flames and explosions to a certain extent, thereby protecting the safety of the pipeline system.

[0042] In a specific embodiment, the fixing rope 5 is made of polymer materials such as glass cloth. Glass cloth can withstand high temperature environment, maintain stable physical properties, and is not easy to burn or produce toxic smoke, thereby ensuring safe use under extreme temperatures. Glass cloth can still maintain stable performance and appearance in the corrosive environment of liquid or gas, and will not corrode quickly, which makes it very suitable for use in highly corrosive industries such as chemical and pharmaceutical industries. Glass cloth is not only soft and easy to process, but also has high tensile strength, which enables it to maintain stable structural performance in various application scenarios. Glass cloth has excellent thermal insulation performance, can effectively reduce heat transfer, and improve the thermal insulation effect of structures such as pipes and walls. Glass cloth is easy to cut, sew and install, which can greatly save construction time and cost and improve work efficiency. Glass cloth is a non-toxic and harmless material that does not cause pollution or radiation to the environment. At the same time, it can also be recycled and reused, which is in line with the development concept of green environmental protection.

[0043] In a specific embodiment, the tube body 33 and the limiting collar 34 are made of steel. The purpose of using the tube body 33 and the limiting collar 34 as steel is the same as the purpose of using the steel material for the protective housing 2.

[0044] In a specific embodiment, Figure 4-Figure 5 A plurality of connecting blocks 36 are installed on the surface of one of the protrusions 31, a movable groove is opened in the connecting block 36, a telescopic rod 37 is transmission-connected in the movable groove, a trapezoidal clamping block 38 is installed at the end of the telescopic rod 37, a clamping spring 35 is arranged on the outside of the telescopic rod 37, and the clamping spring 35 is installed between the connecting block 36 and the trapezoidal clamping block 38, and a trapezoidal jack 39 is opened on the surface of the other protrusion 31. The trapezoidal socket 39 is used in conjunction with the trapezoidal clamping block 38. When the two connecting components 3 are connected, one trapezoidal surface of the trapezoidal clamping block 38 first contacts the entrance of the trapezoidal socket 39. At this time, the trapezoidal clamping block 38 will move toward the inside of the moving groove with the telescopic rod 37, and the clamping spring 35 will be compressed. When the trapezoidal clamping block 38 enters the inside of the trapezoidal socket 39, the other trapezoidal surface of the trapezoidal clamping block 38 contacts the inner trapezoidal surface of the trapezoidal socket 39 and moves. Then, through the elastic force generated by the clamping spring 35, the bottom surface of the trapezoidal socket 39 contacts the surface of the trapezoidal socket 39. At this time, the clamping spring 35 is not completely released. The trapezoidal clamping block 38 is stuck in the trapezoidal socket 39 by the pressure of the clamping spring 35, thereby completing the limit, preventing the two connecting components 3 from being misaligned during the installation process, and facilitating the connection of the two connecting components 3. The inner trapezoidal surface of the trapezoidal socket 39 can also allow the trapezoidal clamping block 38 to move along it, which also facilitates the separation of the two connecting components 3.

[0045] In a specific embodiment, Figure 6A connecting plate 310 is installed on the outer surface of the tube body 33. The connecting plates 310 are arranged in pairs. An arc-shaped pressing plate 311 is installed above the connecting plates 310. A slot is formed between the arc-shaped pressing plate 311, the connecting plate 310 and the outer surface of the tube body 33. The slot formed between the arc-shaped pressing plate 311, the connecting plate 310 and the outer surface of the tube body 33 can embed one end of the aerogel felt, and then insert the other end of the aerogel felt into another slot, so that the aerogel felt can be limited before the fixing rope 5 is tied, and after the aerogel felt is tied, it forms a double limit with the fixing rope 5.

[0046] In a specific embodiment, Figure 7 An arc-shaped hole 21 is opened on the outer surface of the protective shell 2, and a slide groove 12 is opened on the inner surface of the fixed shell 1. A limit spring 13 is installed in the slide groove 12. An arc block 11 is installed at the other end of the limit spring 13. The arc block 11 is transmission-connected in the arc-shaped hole 21 and the slide groove 12. The setting of the arc hole 21 and the arc block 11 is used to determine the installation position of the fixed shell 1. The arc hole 21 is set at the same position on the outer side of the two ends of the protective shell 2. The position of the arc hole 21 of each protective shell 2 is the same, and the end face of the protective shell 2 is aligned with the surface of the limiting ring 34. In this way, when installing the fixed shell 1, one arc block 11 enters the arc hole 21 under the push of the spring, and the other arc block 11 enters the arc hole 21 of the next protective shell 2. The distance between the two arc blocks 11 and the center line of the fixed shell 1 is the same. In this way, the center line of the fixed shell 1 can be aligned with the welding point of the two ends of the tube body 33. The setting of the slide groove 12 is used to hide the arc block 11 in the slide groove 12 when the fixed shell 1 slides along the protective shell 2, and the slide groove 12 can also facilitate the movement of the arc block 11.

[0047] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
